Electrical Plug Connector With Integrated Cable Fixing Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical connectors face issues with mechanical stress leading to connection failure and require additional space for cable fixation, making them cumbersome and space-consuming.
Innovation Solution
An electrical connector design with a combined insulating connector housing that includes latching contact openings and a cable fixation system using two interacting fixing elements, allowing for secure cable attachment without additional tools or space, utilizing a guide for linear movement and slots with webs for clamping cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cables are fixed using a separate cable gland, then mechanical fixation is achieved, but the connector becomes space-consuming and assembly becomes complex
Solution Approach 1:
The patent integrates the cable fixation function directly into the connector housing by forming a cable opening and cable reinforcement structure as integral parts of the housing. This merging of functions eliminates the need for separate cable glands, reducing the number of components and simplifying assembly while maintaining reliable mechanical fixation of the cable
Solution Approach 2:
The connector housing is designed to perform multiple functions simultaneously: it provides structural support, electrical insulation, contact element mounting, and cable fixation. The cable opening and reinforcement structure are formed directly from the housing material, making the housing a multi-functional component that eliminates the need for dedicated cable fixation devices
2Reliability
If additional cable fixation is added, then cable security is improved, but the connector requires additional space
Solution Approach 1:
The cable fixation structure is merged with the connector housing itself. The cable opening and reinforcement structure are formed directly from the housing material through processes like injection molding, eliminating the need for separate fixation components that would occupy additional space. The housing serves dual purposes as both structural element and cable fixation device
Solution Approach 2:
The cable reinforcement structure is nested within the connector housing design. The fixation features are integrated into the housing's internal structure, with the cable opening and reinforcement elements being part of the housing's overall geometry rather than external additions, thus optimizing space utilization
